2. We have to convert the colorspace of this image to RGB because the printer is unable to print this CMYK image

3. When we use below command to do this then color gets sharpened as shown in below screenshot:
Command : convert input.jpg -colorspace sRGB output.jpg
Screenshot of RGB image: http://prntscr.com/o1ca2w

So we just want to change the colorspace from CMYK to RGB and preserve the color intensity or preserve the color contrast
How can we do that?

Please post a link to the actual CMYK file. The critical factor is: does it have an embedded ICC profile? If it doesn't, any conversion to RGB can only be a guess, and there is no "correct" conversion.

Incidentally, I've seen that image before, with a similar "correct" issue.

As you mentioned for the ICC file to put in the current directory for that we have downloaded the sRGB.icc file and placed in current directory and conversion of CMYK to RGB worked fine for the provided command and thanks for that .

We have attached the input image link and output image link of the below command

Your two colorspaces (U.S. Web Coated (SWOP) v2 and sRGB_ICC_v4_Appearance) have different gamuts, meaning some colours can be represented in one colorspace but not the other, so colours don't map 1:1. The ICC give four methods for coping with this; see http://www.imagemagick.org/script/comma ... php#intent and http://www.color.org/iccprofile.xalter . The methods are commonly available in software, but they are not defined standards, so different software can do different things even when the same intent is specified.

When you say "but just with the little color difference", I suspect you are comparing IM's conversion from CMYK to sRGB with another software's conversion from CMYK to sRGB, and viewing the results on a sRGB screen. Perhaps the software systems are using different intents, or perhaps the same intent but different algorithms.

In general, the output cannot be identical to the input because the gamuts are different.

If you want to ensure consistent conversion from CMYK to sRGB, always use the same software with the same intent.

Hi all,
I have a similar problem. When I load in a custom system an image with colorspace CMYK, in the custom system the image has different color.
The color space chanced to sRGB, but the colors are different than CMYK image. Means green color is much darker than rgb image.

How suggested, I add in the setting : "-profile sRGB.icc".
In this way I have solved the problem for an image with colorspace CMYK, but if I upload in my system an image with colorspace RGB, I don't see the preview.

Yes, I have a CMYK image with embedded profile and "-profile sRGB.icc" converts that correctly to sRGB.
I mean that if I add "-profile sRGB.icc" in the setting, I correctly visualize the previews of the images in CMYK, but I don't see the previews of the images in RGB.
( new setting : -intent relative -flatten -sample 1024x768> -quality 95 -profile sRGB.icc -colorspace sRGB -strip -auto-orient
